PPT-Lesson 2.1 Displacement and Velocity

Essential Question How do you calculate the displacement and velocity of an object What is mechanics The branch of physics concerned with motion and forces The subset of mechanics that describes motion without regard to its causes is called kinematics. The different detection systems provide a similar feel of operation thus allowing users to introduce Smart in various scenes A wide array of informationbased tools is also available which offers new digital sensing styles to users Sensing Variation Brown & Wilson’s Definition:. Two . closely related . species have overlapping ranges. In the parts of the ranges where one species occurs alone, the populations of that . species . are similar to the other species and may even be very . What is displacement?. Displacement is how fluid rushes up when an object is added.. displacement occurs when an object is immersed in a liquid, fluid is then pushed up and occupies the object’s place.. Displacement Reactions. Lets look at the reaction between chlorine and potassium bromide. When chlorine is bubbled through potassium bromide solution (colourless), the liquid turns red-brown, because bromine forms.. M. echanics. - the study of the motion of objects. we focus on the language, principles, and laws that describe and explain the motion of objects. Kinematics. is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. . In the next two lectures we will discuss how to measure various types of displacement and motion. These include:. Linear Displacement. Angular Displacement. Linear Velocity. Angular Velocity. Acceleration. Section 7.1a. DO Now – p.370, #1 and 2. Find all values of . x. (if any) at which the function changes. sign on the given interval. Sketch a number line graph of. the interval, and indicate the sign of the function on each. Chapter 11.1. Frame of Reference. Everyone wants to go fast. Whether it is a gangster on a bike or an antelope running away from a cheetah. . To describe either of these motions correctly, we need to have a frame of reference. . Unit 42. Vibrationdata.
